Specification of Letters Patent. Patented Dec. 28. 1.909.

Application filed March 25, 1909. Serial No. 485,581.

To allywhorn it may concern:

Be itknown that I, GEORGE BURESS, of

7 Indianapolis, county of Marion, and State of Indiana, have inventedacertain new and useful Gas-Engine Starter; and I do hereby declare thatthe following is a full,jclear',

andexact description thereof, reference being had to the accompanyingdrawings, in which like numerals refer to like parts.

The object of this invention'is to provide a satisfactory mechanicalmeans for starting gasolene engines, especially designed with referencetense in connection with automobiles. "In such casethe engine can bestarted or actuated by a lever near the seat 0% the driver and withoutthe trouble of go ting out andgoing to the front end of the automobilefor cranking the engine.

The improvementsreferred to herein are made over the construction setforth in my former application, Serial No. 435,415, file d May 28, 1908.v

The chief feature of-the invention consists in providing an adjustabletooth or pawl on the end of the bar that engages the teeth of a ratchetwheel on the engine shaft and turns it sufficiently to start the engine.This adjnstablepawl is a peculiar construction and. not only enables thedevice to always catch and pull through a large are, but it- 'isadaptable to ratchet wheels of varying character or designs of teeth, soas to operate effectively.

Another feature 'of the invention consists in providing a gravity pawlfor preventing backward movement of the ratchet wheel while. the en ineis being started, and means for holding it out of engagement after theengine is started, that is associated with means for holding theactuating pawl or hook out ofengagement after the engineisa starting theengine shaft and associated parts.

Fig'f3 is an end elevation of the engine casing of the automobilewiththe parts in vertical transverse section showing the device theengine shaft.

in condition for starting the engine. Fig. 4 is a section on the line tof Fig. 3. Fig. 5 is an enlarged side elevation of the bar and pawl foractuating the ratchet wheel on Fig. 6 is a section on the line 66 ofFig.

In detailthere is shown in the drawings the frame 10 of an automobilewith seat 11, steering wheel 12, engine casing 13,- fonr-- cylinderengine 14, front casing 16, front axle17' and front wheel 18.

19 is the engine shaft on which the ratchet wheel 20 is secured. Theengine shaft has a squared end 21 and adapted to receive the squaresocket end of the crank 22. The shank of the crank 22 is mounted in theframe bar 23 and normally pushed outwardly by spring 24 as far as thepin 125 will permit," so that the startingcrank will with the engineshaft.

For starting the engine I provide a hell crank lever 25 fulcrumedbetweenits ends at 26 with a starting bar 27 extending from one end of the bellcrank lever across and immediately to the rearof the upper part of theratchet wheel 20, and on the free end of said bar 27 I mount theadjustable pawl 01' tooth 28, which is adapted to engage the teeth ofthe ratchet wheel when the bell cranklever is actuated and the bar 27withdrawn and thus give the ratchet wheel a start. This adjustable pawlconsists of a tooth portion extending substantially at right angles fromthe body portion thereof, which body portion is at its upper'end pivotedon the pin 29, and an adjusting pin or set screw 30 extends through thebody portion of said awl 28 and through a slot 31 in the bar 2 whichslot is curved concentrically with the pin 29. This construction enablesme to give the toothor pawl 28 any desired pitch and thus get the best.catch possible on the teeth of the ratchetwheel. The pull of the bar 27istangential so it will tend to revolve the wheel 20.

One end of the bell crank lever 25 is connected by a link 35 withanother bell crank lever 36 fulcrumed at 37 to the side of the frame andwith a connecting rod 38 leading therefrom to a third bell crank lever39 fulcrumed at 40 to the side of the frame and. from that an adjustablelink 40 leads to the lower end of the vertical lever 41, which isfnlcrumed at 42 in the side of-the frame.

be normallv held out of locking engagement When the upper end of thelever 41 is drawn theengine. The pawl 50, would hold them in theirpositions until a new hold could be gotten by the bar 27 and pawl 28 forfurther rotation of the engine shaft.

The actuating pawl 28 is held normally out of engagement with ratchetwheel 20 by cable 60 that runs over pulleys 61 and 62 back to the pedalmechanism 63. The pawl for preventing backward movement is also held outof engagement with the ratchet wheel by cable Gt that passes the pulleys65 "and 66, and connects with the cable so that theme means hold boththe pawlmechanisms vout of engagement with wheel 20 after the engine hasbeen' started.

What-I claim as my invention and desire to secure'by Letters Patent is:

1. In combination with the shaft of an explosive engine, of agear'secured thereon,

oscillatory means pivoted away from the gear and its axisfa curved'barpivoted at one end to said oscillatory means and extending beside saidgear, and an'adjustable pawl on the other end of ..sai'd bar forengaging the teeth at one sideof the gear during the movement of saidbar, whereby said gear will be actuated to start thefengine.

2. In combination with'the shaft of an explosive engine, of a gearsecured thereon,. .oseillatory'means pivoted away from the gear and itsaxis, a curved, bar pivoted at one end to said oscillatory means andextending beside said gear, a pawl on the other end of said bar andhaving a body portion pivoted on said bar, a tooth projectfixed mysignature in the ing laterally therefrom in position to engage the teethof said gear and cause the rotation thereof when said bar is actuated, aclamp extending through the body portion of said pawl, and a slot insaid bar for hold ing the pawl in position to give the tooth the desiredangular relation to the teeth of the gear. v

3. In combination with the shaft of an explosive engine, of a gearsecured thereon, oscillatory means pivoted away from the gear and itsaxis, a curved bar pivoted at one end to said oscillatory means andextending beside said'gear, an adjustable pawl on the other end of saidbar for engaging the teeth at one side of the gear during v movement ofsaid bar, whereby said gear will be actuated when theengine is started,

and a gravity pawl in position to catch the teeth of said gear under theinfluence of gravity and prevent the backward move:

ment thereof, and means for holding said 7 pawl disengaged from saidgear.

4. In combination with the shaft of an explosive engine, of a gearsecured) thereon, oscillatory means pivoted away from the gear and itsaxis, a curved bar pivoted at one end to said oscillatory means andextending beside saidgear, an adjustable pawl on the other end of saidbar for engaging the teeth at one side of the gear during movement ofsaid bar, whereby said gear will be actuated when theengine is started,

and a single means. for'holding both the actuating pawl and the pawl forpreventing backward movement of said gear away from said gear after theengine has been started.

In witness whereof, I have hereunto afwitnesses herein named. I I
